Creating X-rays with a standard vacuum tube (2012x18)

Air date: Jul 08, 2012

I forced an RCA 811A tube to produce some X-rays by operating the tube in cold-cathode mode at about 20KV and 150uA. The glass fluoresces nicely, but I didn't get any light from my X-ray intensifier cassette. MightyOhm's geiger counter kit: http://mightyohm.com/blog/products/geiger-counter/
